Symptom: In /var/log/cups/error_log there is a message
(/usr/lib/cups/filter/hpcups) crashed on signal 11. and printer
doesn’t print anything. The problem is that hpcups is buggy in Ubuntu
19.04.
A solution is to install HP printer driver from sources from
https://developers.hp.com/hp-linux-imaging-and-printing. There
are several problems with this however.
- Delete all printer configurations from
/etc/cups/printers.conf.
- First download and run HPLIP main source hplip-3.19.8.run and a
plugin for it hplip-3.19.8-plugin.run. Use whatever version is
latest from HP site.
- Try to run
./hplip-3.19.8.run and install as much as there is
installing.
- In my case plugin installation failed and I couldn’t go on.
Plugin tries to access keyserver pgp.mit.edu which fails to
produce any keys. It helped me to execute the following commands:
gpg --keyserver pool.sks-keyservers.net --recv-keys 0x4ABA2F66DBD5A95894910E0673D770CDA59047B9
/usr/bin/gpg --homedir /home/gregory/.hplip/.gnupg --no-permission-warning --keyserver pool.sks-keyservers.net --recv-keys 0x4ABA2F66DBD5A95894910E0673D770CDA59047B9
Close hplip installation and try to run hp-setup -g.
I noticed that when listing libraries I got the same errors as in
this comment. It is necessary to fix all of the libraries that it
complains about using symlinks.
Plugin installation successfully finishes. It is possible to finis
hp-setup and create a new printer configuration now.
The problem with hpcups doesn’t go away because HPLIP driver
didn’t modify already installed Ubuntu version. It is necessary to
uninstall it from the system with sudo apt-get remove printer-driver-hpcups.
Then don’t do sudo apt autoremove because this will install
necessary packages and HPLIP installation fails. I also had to
install python3-pyqt4 to proceed.
Run ./hplip-3.19.8.run again this time to install its own
version of hpcups.
If plugin has to be installed again and you’re getting error:
Python gobject/dbus may be not installed what helped me was to
run plugin installation manually ./hplip-3.19.8-plugin.run
--confirm.
This creates a /tmp directory with self extracting archive
contents and asks whether to execute command
./hplip-plugin-install -v 3.19.8 -c 64
Manually cd to the unpacked directory in /tmp and execute this
command. Plugin installation is successful, finally!
